How much feed per kilo of fish?
Feed conversion ratio (FCR) tells you how many kilograms of feed it took to add one kilogram of fish. It's the single most useful number for spotting waste - a rising FCR usually means something's off before you'd notice it any other way. Enter your feed and weights to see where you stand.
What FCR means. An FCR of 1.5 means it took 1.5 kg of feed to grow 1 kg of fish. Cheaper feed with a worse FCR can still cost more per kilo of fish than pricier feed that converts well.
⚠️ A rough working figure, not a lab measurement. FCR shifts with water temperature, fish size, feed quality and how much feed drifts uneaten to the bottom. Track it over time rather than trusting a single reading - the trend tells you more than the number.
